back hammers
Our DTH back hammers are designed to break or destroy obstacles that get stuck on the drill bit, allowing you to resume drilling operations faster while minimizing downtime and repair costs. They can be installed between the drill rod joint and the rotary head to produce an effective reverse impact and vibration that can be used to crush hard materials such as concrete and rocks, helping to clean the drill bit and speed up drilling operations.
Our DTH Back Hammers consist of only three parts and a plastic casing that guides exhaust emissions and acts as a silencer to reduce noise pollution in the surrounding environment.
